WATER GAUGE.

Application filed April 9, 1926, Serial No, 100,958.

This invention relates to devices for de termining the water level insteam boilers and has for an object the provision of a gauge or valvewhich may be operated to determine whether or not water within theboiler is at the proper level.

Another object of the invention is the provision of a device of theabove character which is simple in construction, reliable in use, may beeasily installed and will effectually prevent spraying of the boiler byescaping steam or water.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings Figure 1 is a fragmentary sectional view illustratingthe use of the invention.

Figure 2 is a similar view partly in elevation.

Figure 3 is an end view of the body of the valve.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the reference character 10 indicates thebody of the gauge or valve which is provided at one end with anextension 11. The extremity of this extension is exteriorly threaded forremovable engagement with a threaded opening provided in a boiler 12 orother liquid container.

The body is provided with a substantially L-shaped passage 13 and oneend of this passage opens into the boiler 12. The opposite or other endof the passage 13 is counterbored or enlarged as shown at 15 and hasthreadedly secured therein a sleeve or thimble 16. This sleeve orthimble is provided with an opening 17 which extends longitudinallytherethrough and this opening provides a restricted outer end for thepassage 13. The opening 18 is surrounded at its in ner end by a valveseat 18 which receives a valve 19, the latter being preferably of thegravity ball type.

Extending from the body 10 are spaced arms 20 between which is pivotallymounted as shown at 21, an operating lever 22. Extending from the lever22 is a substantially Renewed November 23, 1928.

L-shaped arm 23 which operates within the restricted portion or opening17 of the passage 13 and may be moved inward to unseat the valve 19.Movement in this direction is resisted by a spring 24 which is mountedupon a pin 25.

Normally, the parts are in the position illustrated in Figure 1 and bymoving the arm 23 inward, the valve 19 may be unseated so that water maybe permitted to flow through the passage 13 and the level of the waterwithin the boiler determined.

If desired, the device may include an auxiliary valve 26 whose rod 27extends through the body 10. The valve 26 is normally arranged in openposition so that water may flow into the passage 13. The valve 26 mayhowever be moved to closed position so as to shut water off from thepassage in case of emergency, or, when adjusting or repairing thedevice.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaim.

Having described the invention what is claimed is A valve comprising abody having passage ways arranged at right angles to each other anddisposed in communication, an extension formed with said body and beingthreaded for securing the body in connection with a fluid container in amanner whereby one of said passage ways extends at right angles to saidcontainer, a gravity operated ball in the other passage way, a thimbleformed with an opening terminating in a seat for said ball and beingthreadedly secured in said body, a yieldingly resisted member includingan L-shaped arm having a portion thereof passing through said openingfor unseating said ball upon movement of the memher in one direction, avalve stem in the passage way disposed at right angles to the container,a valve on the stem and being disposed in said container to cooperatewith a seat formed on the extension for controlling the flow of fluid tothe respective passage ways.

In testimony whereof I affix my signature.

CORNELIUS BROWN.
